Real Mike Ditka Meets Drunk Mike Ditka At Bachelor Party Turn Up

A bunch of drunk guys on a bachelor party weekend thought it would be funny to dress the groom up like Mike Ditka on Friday and go to Ditka's steakhouse in Chicago.

Turns out ... BEST. IDEA. EVER!!!

The bachelor, David Barnett, lives in Florida -- but his buddies threw the party in Chicago so they could party during NFL Draft weekend. Barnett's also a huge Bears fan.

And because every bachelor party needs drunken buffoonery ... the guys made Barnett dress up like Da Coach for their dinner at Ditka's.

As fate would have it, Mike was actually in the restaurant that night ... heard about his boozy doppelganger ... and came over for a face-to-legendary-face meeting.
